We now had left him, passing on our way,
When I beheld two spirits by the ice
Pent in one hollow, that the head of one
Was cowl unto the other; and as bread
Is raven'd up through hunger, th' uppermost
Did so apply his fangs to th' other's brain,
Where the spine joins it. Not more furiously
On Menalippus' temples Tydeus gnaw'd,
Than on that skull and on its garbage he.
